Variants

LLVMModuleFlagBehaviorError = 0

Emits an error if two values disagree, otherwise the resulting value is that of the operands.

LLVMModuleFlagBehaviorWarning = 1

Emits a warning if two values disagree. The result value will be the operand for the flag from the first module being linked.

LLVMModuleFlagBehaviorRequire = 2

Adds a requirement that another module flag be present and have a specified value after linking is performed. The value must be a metadata pair, where the first element of the pair is the ID of the module flag to be restricted, and the second element of the pair is the value the module flag should be restricted to. This behavior can be used to restrict the allowable results (via triggering of an error) of linking IDs with the Override behavior.

LLVMModuleFlagBehaviorOverride = 3

Uses the specified value, regardless of the behavior or value of the other module. If both modules specify Override, but the values differ, an error will be emitted.

LLVMModuleFlagBehaviorAppend = 4

Appends the two values, which are required to be metadata nodes.

LLVMModuleFlagBehaviorAppendUnique = 5

Appends the two values, which are required to be metadata nodes. However, duplicate entries in the second list are dropped during the append operation.

Trait Implementations

impl Clone for LLVMModuleFlagBehavior

fn clone(&self) -> LLVMModuleFlagBehavior

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for LLVMModuleFlagBehavior

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for LLVMModuleFlagBehavior

fn eq(&self, other: &LLVMModuleFlagBehavior) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
